Operation of each component
IS350/250_U (OM53758U)
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■Linked mirror function when reversing (if equipped)
●When either “L” or “R” of the mirror select switch is selected, the outside rear view mir-
rors will automatically angle downwards when the vehicle is reversing in order to give a
better view of the ground. To disable this function, select neither “L” nor “R”.
●If the mirror angle adjustment switch is operated while the linked mirror function is in
operation, the angle and position of the mirrors can be remembered, and the mirrors
will operate at the angle adjusted to the la st time the linked mirror function was oper-
ated.
However, because the mirrors move based on the angle they are in when the linked
mirror function is not operating, the mirror angle when the linked mirror function is
operating will also be changed if the mirrors are adjusted while the function is not oper-
ating.
■When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. ( P. 3 5 0 )
■Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( P. 1 2 3 )
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. ( P. 1 3 2 )

■When starting off on an uphill
The hill-start assist control will activate. (P. 2 3 4 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and th e road will be slippery.
●Drive carefully when it starts to rain, becau se the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indica te sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When the brake pedal is depresse d while sport mode is selected

• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
